Greek Yarrow Achillea ageratifolia
ABOUT
Achillea ageratifolia, commonly known as Greek yarrow, is a perennial herb distinguished by its silvery-green foliage and small, daisy-like flowers. The leaves of this plant are narrow and elongated, resembling those of its close relatives in the yarrow family, with a somewhat woolly or felt-like texture, lending it a soft, matte appearance. These leaves form a low-growing mat over the ground. The flowers of Greek yarrow are typically white or cream-colored, each with a tight cluster of tiny, prominent floral centers surrounded by a few flat, petal-like rays giving it a classic yet delicate aesthetic. The blossoms are arranged in compact, flat-topped clusters, creating a cushion of blooms that can add a touch of classic charm to any garden setting. The overall look of the plant is one of subdued color and fine texture, making it a pleasing addition to rock gardens, borders, and as groundcover.

- Toxicity
To humans
Achillea ageratifolia, commonly known as Greek Yarrow, is not typically known to be toxic to humans. Most members of the Achillea genus are not poisonous and some are actually used in traditional herbal remedies, though they may cause allergic reactions in some individuals, particularly those with sensitivity to plants in the Asteraceae family. However, it is important to note that individual reactions can vary greatly and it is generally advised to avoid ingesting any part of a plant unless it is well-known to be edible or if you have expert knowledge. If the plant is somehow poisonous and ingested, symptoms could theoretically include stomach upset, nausea, vomiting, or diarrhea, but specific toxicity symptoms of Greek Yarrow to humans are not widely documented.
To pets
Achillea ageratifolia, or Greek Yarrow, is not typically recognized as toxic to pets such as dogs and cats. Most species in the Achillea genus have no known severe toxicity to pets, although individual animals might have allergies or sensitivities to these plants. As a general precaution, pet owners should prevent pets from consuming plants that are not part of their normal diet since ingestion might lead to mild gastrointestinal upset, like vomiting or diarrhea, due to the plant's essential oils and other constituents. If an animal does consume Greek Yarrow and shows signs of distress, it is advisable to consult with a veterinarian. Always exercise caution and keep an eye on your pet for any adverse reactions after ingestion of any plant material.

- Water
Greek Yarrow (Achillea ageratifolia) prefers to be watered thoroughly but infrequently. It is a drought-tolerant plant, so it's crucial to allow the soil to dry out between waterings. During the growing season, you may water the plant once every 1-2 weeks, depending on weather conditions. Each watering session should provide enough water to wet the soil to a depth of about 8-10 inches; this could be approximately 1-2 gallons for a mature plant, depending on the soil and pot size. Reduce the watering frequency during the winter months when the plant is not actively growing.
- Light
Greek Yarrow thrives in full sun conditions, where it receives at least 6 hours of direct sunlight each day. The plant performs best when placed in a location where it has clear, unfiltered access to sunlight. Avoid shady spots as inadequate light can result in leggy growth and fewer flowers.
- Temperature
Greek Yarrow can endure a wide range of temperatures; however, it prefers a temperate climate. It is hardy and can survive temperatures as low as 5 degrees Fahrenheit and as high as 90 degrees Fahrenheit, although it thrives best between 60 and 75 degrees Fahrenheit.
- Pruning
Greek Yarrow should be pruned to maintain its shape, encourage more robust growth, and enhance flowering. Deadhead spent blooms throughout the flowering season to promote continuous blooms. Cut back the plant in late fall or early spring to tidy up any dead or damaged foliage and stimulate new, healthy growth. Pruning can be done every year or whenever the plant appears overgrown.
- Cleaning
As needed
- Soil
Greek Yarrow (Achillea ageratifolia) thrives in well-draining soil with a pH ranging from 6.0 to 7.5. A suitable soil mix can be made from one part garden soil, one part sand, and one part compost to ensure good drainage and fertility. Adjust the soil mix with limestone or sulfur to achieve the desired pH level.
- Repotting
Greek Yarrow does not require frequent repotting and can often be left undisturbed for several years. Repotting can be done every 3-4 years, or when you notice the plant has outgrown its current container.
- Humidity & Misting
Greek Yarrow prefers a relatively dry environment and is tolerant of low humidity levels. It does not require high humidity to thrive, making it well-suited to dry climates and conditions typical of temperate regions.
- Suitable locations
Indoor
Place in sunny spot, minimal water, well-draining soil.
Outdoor
Plant in full sun, well-drained soil, trim after flowering.
Hardiness zone
3-8 USDA
- Life cycle
Achillea ageratifolia, also known as Greek Yarrow, starts its life cycle as a seed, which upon finding suitable conditions, germinates and develops into a seedling. The seedling grows into a rosette of basal leaves, establishing a root system and storing energy. As it matures, the plant develops a flowering stalk, and during the flowering stage, it produces compact clusters of small, white, daisy-like flowers. Following pollination, typically by insects, the flowers turn into fruits, which are small, dry, one-seeded achene. The seeds are dispersed by wind, water, or animal activity, allowing for colonization of new areas. Greek Yarrow is a perennial plant, thus after flowering, it can enter a period of dormancy during adverse conditions, only to regrow and repeat the cycle in the following growing season.
- Propogation
Propogation time
Spring to early summer
The Greek yarrow, or Achillea ageratifolia, is commonly propagated by division, which is often seen as the most popular method for this perennial plant. The best time for division is typically in the spring or early fall, when the plant is not in active bloom. To propagate by division, the gardener should carefully dig up the parent plant, ensuring as much of the root system is intact as possible. Then, using a sharp tool, the clump is gently separated into smaller segments, each with a portion of the root system and several shoots. These segments can be immediately replanted in well-drained soil, spaced approximately 12 to 18 inches (30 to 45 centimeters) apart to allow room for growth. Regular watering after planting helps the divisions to establish, and with proper care, they will develop into strong, flowering plants by the next season.
